Abstract: A system and method for determining eye surface contour using multifocal keratometry is disclosed. The system includes a light source, a light detector, a processor, a non-transitory machine-readable medium communicatively coupled to the processor, and instructions stored on the non-transitory machine-readable medium. The instructions, when loaded and executed by the processor, cause the processor to project a light, using the light source, onto a plurality of surfaces of an eye; create, using the light detector, an image of a plurality of reflections, each of the plurality of reflections created by reflecting the light off of one of the plurality of surfaces of the eye; determine that the plurality of reflections are in focus in the image; and calculate, based on the determination, a curvature of the plurality of surfaces of the eye based on the image.

Abstract: Both visible and IR cameras are integrated without an increase in an optical stack height of a surgical microscope used for ophthalmic surgery. The IR camera may be used to directly and intraoperatively capture a scanning OCT measurement beam, which uses NIR light that is invisible to the human eye. An IR image from the IR camera taken from the same surgical field as displayed intraoperatively to a user of the surgical microscope may be displayed in an ocular to the user, enabling visualization of a location of an OCT scan along with actual visible images of the surgical field.
